Fishing licenses go on sale February 18 each year, the beginning of prime fishing, and are valid through the last day of February. Most licenses, except the Lifetime Sportsman License and specialty licenses, such as Wheelchair, Disabled Veteran, SSI (Supplemental Security Income), and Blind Fishing licenses, are available from most county clerks, sporting goods stores, hardware stores, boat docks, online, and from all TWRA offices.
